  2. Look for natural splits or divisions in the plant. If there are none, create a split by carefully pulling the plant apart at its base.
  3. Use a clean, sharp knife to cut the plant into sections. Each section should have its own roots and at least one set of leaves.
  4. Be careful not to damage the roots or leaves during the process.

Replanting the Divisions

After you have split the plant, it’s time to replant the divisions. Here are the steps to follow:

  4. Wait a few days before watering the plant again to allow it to adjust to its new environment.

When Not to Split Your Split Rock Plant

It is generally not recommended to split a split rock plant if it is not actively growing or if it is in poor health. Splitting a plant that is not actively growing or is unhealthy can cause additional stress to the plant and may not result in successful propagation. It is also not recommended to split a split rock plant during the winter months, as this is typically a period of dormancy for the plant.

Additionally, splitting a plant that is too small may not be advisable, as it may not have enough energy reserves to support multiple plants. It is important to assess the health and growth patterns of the plant before attempting to split it. If you are unsure whether your split rock plant is ready to be split, it may be best to consult a plant care expert or horticulturist for guidance.


Splitting your Split Rock plant can be a great way to propagate the plant or keep it from outgrowing its current pot.

Cultivation of the Split Rock Plant


The split rock plant can be propagated through seeds or by division. To propagate through seeds, collect the seeds from the plant after the flowering season. Soak the seeds in water for 24 hours before planting them in sandy soil. Keep the soil damp but not too wet until the seeds germinate.

To propagate through division, wait until the plant has produced offsets. Carefully remove the offsets and plant them in sandy soil. Water the offsets sparingly until they have established roots.

Growing Conditions

Split rock plants prefer bright, unmodified light and dry, arid, and semi-arid climates. They thrive in the spring and autumn seasons and detest cold weather. When cultivated outdoors, split rock plants perform best in warmer climates (in 9-11 USDA regions).

When dealing with a split rock plant, it is recommended to use a soil mix consisting of 1 part peat moss to 1 part loam to 2 parts coarse sand with small pebbles added to ensure good drainage. Very little water is needed during the growing season, and you do not fertilize the plants. Make sure NOT to water on the plant itself. Water directly in the soil.

Pests and Diseases

Split rock plants are generally pest and disease-free. However, they can be susceptible to mealybugs and spider mites. To prevent infestations, inspect the plant regularly and remove any affected areas immediately.

Overwatering can cause root rot, which can be fatal for the plant. To prevent root rot, make sure the soil is well-draining and avoid watering the plant too frequently.

Care and Maintenance of a Split Rock

Taking care of a split rock is easy, and it only requires minimal maintenance. Here are some tips on how to keep your plant healthy and thriving.


Split rock are drought-tolerant succulents that can survive long periods without water. Therefore, it’s essential to avoid overwatering your plant, as this can lead to root rot. We recommend watering your split rock plant once a month during the growing season (spring and summer) and once every two months during the dormant season (fall and winter).

When watering your split rock plant, make sure to soak the soil thoroughly and let the excess water drain out of the pot’s bottom. Avoid getting water on the plant’s leaves or stem, as this can cause rot. We also recommend using a well-draining soil mix that allows excess water to drain away quickly.


Split rock do not require frequent fertilization, but you can give them a boost during the growing season (spring and summer) by applying a balanced, water-soluble fertilizer. We recommend diluting the fertilizer to half-strength and applying it once a month.

Avoid fertilizing your split rock plant during the dormant season (fall and winter), as this can cause the plant to grow too quickly and become weak and leggy.


Split rock plants do not require pruning, but you can remove any dead or damaged leaves or stems to keep your plant looking neat and tidy. We recommend using clean, sharp scissors or pruning shears to avoid damaging the plant.

In conclusion, taking care of a split rock plant is easy and straightforward. By following these simple tips, you can keep your plant healthy and thriving for years to come.
